Pipefitting to insert a 60mm Fan into a DN50 Pipe.
You need to place 4 4*6*6mm or 4*4*6mm Knurled Nuts to secure the M4 Bolts
you need a Scew that's about 15mm longer than the Thickness of the Fan (e.g.: 25mm FAN, 40mm Screw; 10mm Fan, 25mm Screw (a 20mm screw worked for me too in this case)
It is designed to fit a M4 Socket Screws for an Allen key
